Ho lokolloa ha Linux kernel 5.6 ho reriloe bofelong ba Hlakubele. Sengoliloeng sa rona kajeno, re tšohla liphetoho tse tlang - sistimi e ncha ea faele, protocol ea WireGuard, le liapdeite tsa mokhanni.

Protocol ea VPN e lebelletsoeng nako e telele
David Miller, ea okametseng tsamaiso ea marang-rang ea Linux, o ile a etsa qeto ho kena mokokotlong oa WireGuard. Ena ke kotopo ea VPN e ntlafalitsoeng ke k'hamphani ea ts'ireletso ea tlhahisoleseling Edge Security. mohopolo lilemo tse peli tse fetileng - ebe eena Linus Torvalds ka boeena - leha ho le joalo, ts'ebetsong e ile ea chechisoa. Morero o ne o amana haholo le likarolo tsa crypto tsa Edge Security. Empa likhoeling tse tšeletseng tse fetileng, bangoli ba protocol e ncha ba ile ba sekisetsa le ho li-API tsa Crypto tse tšehetsoeng ke kernel.
Ho na le hore nakong e tlang WireGuard e tla khona ho nkela OpenVPN sebaka. Ho latela , phallo ea protocol e ncha e phahame ka makhetlo a mane ho feta ea OpenVPN: 1011 Mbps khahlano le 258 Mbps. Empa mona ke habohlokoa ho hlokomela hore phetoho ho Crypto API e tloaelehileng e ka mpefatsa tshebetso.
Tšobotsi e 'ngoe ea WireGuard ke hore , le haeba mosebelisi a fumane aterese e ncha ea IP, mme a rarolla mathata a ho tsamaisa ka boikemelo. Bakeng sa merero ena, senotlolo sa poraefete se tlameletsoe ho sebopeho se seng le se seng sa marang-rang. E hlahisoa ka . Encryption ka boeona ho ChaCha20 le algorithm . Li nkoa e le li-analogue tse ntlafalitsoeng tsa AES-256-CTR le .
Sistimi e ncha ea faele
Ka tsamaiso ena Li-Zonefs tse fanoeng ke baenjiniere ba Western Digital. E etselitsoe ho sebetsa le lisebelisoa tsa polokelo ea libaka (). Tsena ke li-block drives, sebaka sa aterese se arotsoeng ka libaka (mohlala, NVMe SSD). Sistimi ea faele e u lumella ho tšoara sebaka se seng le se seng joalo ka faele - ke hore, sebelisa li-API tse khethehileng sebakeng sa ho fihlella polokelo. Ho sebelisoa mokhoa o ts'oanang ho li-database tsa RocksDB le LevelDB. E etsa hore ho khonehe ho fokotsa litšenyehelo tsa ho tsamaisa khoutu eo qalong e neng e etselitsoe ho sebetsa le lifaele.
Linux e se e ntse e na le karolo ea ho sebelisana le lisebelisoa tsa block. Ka mofuta oa kernel 4.13 dm-zoned module. E hlahisa drive ea zoned e le sesebelisoa se tloaelehileng sa block, mme Zonefs e tla ba eona e 'ngoe.

Ntle le ho hlahisa sistimi e ncha ea faele, baetsi ba Linux kernel ba entse liphetoho ho tse teng. E ne e mekhoa ea ho hatella / bakeng sa F2FS, tšehetso ea bona e tla lula e le liteko hajoale. E tla tlameha ho sebelisoa ka letsoho nakong ea ho kenya karohano (khetho compress_algorithm). Hape ntlafatsa EXT4 - E amahanngoa le ts'ebetso ea I / O e tobileng. Sephutheloana sa ntlafatso se hlahisitsoe ke Ritesh Harjan, moenjiniere oa IBM. Ka , maemong a mang patch e ka ntlafatsa ts'ebetso ea sistimi ea faele ka 140%.
Lintlafatso tsa bakhanni
Mokhanni e mocha o tla hlaha kernel cpuidle_cooling... Ea hae - pholisa CPU / SoC ka ho kenyelletsa lipotoloho tse sa sebetseng nakong ea ts'ebetso. Ka tsela e itseng, e ts'oana le mokhanni oa PowerClamp bakeng sa li-processor tsa Intel, empa ha e khethe meralo. tsamaiso litsebi tse tsoang ho Linaro tse ntlafatsang software ea mohloli o bulehileng bakeng sa liforomo tsa ARM.
Hape tšehetso bakeng sa likarete tsa video tsa letoto la GeForce 20 (TU10x). Mokhanni ea tsamaellanang o entsoe ke Ben Skeggs ho tsoa morerong oa Nouveau. Ka bomalimabe, GeForce 16 (TU11x) e tla lula e le "ho feta" hajoale. Nvidia ha e fane ka litšoantšo tsa firmware tse hlokahalang ho qala karete. Hape, likarete tse ncha tsa video tlasa Linux li ka ba le mathata a ts'ebetso ka lebaka la khaello ea ho khutlisa - taolo ea frequency ea othomathike. Ho fumanoe nakong e fetileng hore bakhanni ba Nouveau 20-30% butle ho feta ba pele.

E 'ngoe ea mantlha e ncha USB4. Ho latela liphetoho baenjiniere ba Intel. Ba fetotse codebase e teng e amanang le Thunderbolt - ke mela e ka bang likete tse peli.
Ehlile, tsena ha se lintlafatso tsohle tse tlang ho kernel - mohlala, tšehetso bakeng sa lisebelisoa tse eketsehileng tsa peripheral le lisebelisoa tsa marang-rang. Hape, kernel 5.6 e tla ba kernel ea pele ea 32-bit moo . Qetellong ea January, baenjiniere liphetoho tsa ho qetela ho nfsd, xfs, alsa le v4l2. Ba tšepa hore lilemong tse leshome le metso e robeli tse setseng, basebelisi le bahlahisi ba kabo ba tla ba le nako ea ho fallela ho kernel 5.6 (kapa liphetolelo tsa eona tse latelang).
